A positive point charge q is brought near a neutral metal sphere.

A positive point charge q is brought near a neutral metal sphere.

A positive point charge Q is brought near a neutral metal cube.

An agent is moving a positively charged body towards another fixed positive charge. The work done by the agent is

A conducting ball is given a certain charge and fixed at point P. An another point charge of mass 1 gm and charge 20muC when kept at Q (3m, 9m) starts moving with acceleration veca=(1.08hati+1.44hatj)ms^(-2) . The potential at Q is +720 volt. Calculate (a) charge given to ball (b) position of the ball.

What will happen to the strips of a positively charged electroscope when a positively charged and another negtively charged bodies with equal magnitude of charge are brought simultaneously in contact with the cap of a positively charged electroscope?
